PAPER-MAKING-MACHINE DRIVE.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed January 26, 1907. Serial No. 354,231.

- ticularly pointed out in claims.

Referring to the drawings, Figures 1 and are a diagrammatic elevation ofcertain parts of a paper making machine showing my invention appliedthereto. Figs. 3 and 4 are a top plan view of the parts shown in Figs. 1and 2. Figs. 2 and 4 are continuations of the same machine, parts ofwhich i shown in these drawings as it is not thought necessary for thepurpose of illustrating the present invention.

11, 11 designates a plurality of I-beams which are arranged to supportthe floor l0, and also support the various parts of the drivingmechanism for the paper making machine itself in a peculiar manner whichI have invented.

In Fig. 6 I have shown. one of the presses 40 on a somewhat enlargedscale. This press is of ordinary construction but is supported anddriven in a novel manner which I have invented. 12, 12 designatebrackets which are arranged to be supported by the are shown in Figs. 1and 3, so that these fig 1 ures are designed to be taken together. Fig.51s a top plan view taken under the founshows the engine and a system ofrope-drive connecting the engine to a series of countershafts. Fig. 6 isa sectional side elevation of a press, one of the units in a papermaking machine, showing certain parts of its driving mechanism. Fig. 7shows a modification of one part of my invention. In this figure a gas,air, steam or other fluid pressure device is shown for throwing thedriving gear into and out of operative relation with the units of thepaper making machine.

Like characters of reference designate corresponding parts in all of thefigures.

10 designates the operating floor of a pa per making machine which isarranged to support the various units of the machine in a manner which Iwill more fully describe hereinafter.

20 designates the Fourdrinier wire commonly used in a paper makingmachine, one portion of which passes over a breast-roll 21 and the otherend of which passes over a roll 31 of the couch 30. The under portion ofthis wire is carried over a series of small rolls 22, 22 in the ordinarymanner.

40, 50 and designate three presses of the machine.

designates the drier and 80 the calender. The other units of themachine, that is, the reels, slitter and winder, are not I-beams 11 bymeans of bolts 13 which pass through holes which may be drilled throughthe webs of the I-beams at the desired points. These brackets 12, 12 arearranged to be attached to and to support horizontal beams 14 to whichthe frames or pedestals 41 of the press are attached. A bearing 42,which is arranged to support the shaft 43 of a pinion 44, is alsosupported by these horizontal beams 14 and is arranged to be verticallydation floor of the machine proper and' adjustable by means of thewedge-shaped blocks 45 and their adjusting screws 45 46designates themain shaft of the press 40 which is supported in a bearing 47, whichbearing is mounted upon the frame or pedestal 41 and which is arrangedto be vertic-ally adjustable by wedge-shaped blocks and adjusting screwssimilar to those just described. 48 designates a spur-gear which ismounted upon and keyed to the shaft 46 and which is arranged to be inmesh with the pinion 44. 49 designates the lower roll of the press 40and this roll is also rigidly attached to the shaft 46 and arranged tobe driven thereby. 49 designates the upper roll of the press 40. Thecenters of the different units in machines of this character are atdiflerent heights above the operating floor. It has heretofore beennecessary to construct the supporting parts of these mechanisms in sucha manner as to provide these diiferences in height.

By using the construction which I have above described it is possible touse frames or pedestals, such as 41, of the same size for all of theunits and to obtain the required difierences in height by attaching thebrackets 12 to different portions of the webs of the I-beams 11. In Fig.6 the brackets 12 are shown attached to the upper portion of these websand the dotted lines in this figure designate the brackets in theirlowest position on these Webs. In Fig. 7 an intermediate position of thebrackets 12 on the webs of the I-beams 11 is shown. In this manner thevarious units may be supported at the required heights, and any fineradjustment which may be necessary may be obtained by means of thewedgeshaped supporting blocks and their adjustmg screws.

90 designates a steam engine which supplies motive power to thismachine. This engine may be variable in speed or it may be replaced byspeed changing device driven by any desired motive power. 91 is itsflywheel. This fly-wheel is connected by a belt 92* to a pulley 92 whichis rigidly mounted upon a countershaft 93.

94:, 94. designate rope-drive sheaves which are rigidly mounted upon thecountershaft 93 and which are arranged to be driven by the engine 90.

95, 95 designate a plurality of driving ropes which cooperate with therope-drive sheaves 9a, 9a and a plurality of other ropedrive sheaves 9696 96 96 96 96 and 96 each of which is mounted upon one of a series ofcountershafts such, for example, as the countershaft 97 A cone pulleysuch as 98 is attached to one end of each of these countershafts, andbetween the ropedrive sheaves and the cone pulleys a friction clutchsuch as 99 is interposed.

100 designates a tension device for the driving ropes which comprise atraveling sheave 101 in a loop of the driving rope 95 and the weight 102which is arranged to move the traveling sheave 101 and take up any slackin the driving rope 95. At 103 a similar tension device is shown inanother portion of the driving rope.

The cone pulley a3 is attached to the shaft 13 of the press 40, and asimilar cone pulley is attached to a similar shaft or shafts of theother units. This cone pulley 43 is connected with the cone pulley 96 bya belt 4.3 and any of the wellknown beltshifting devices commonly usedin mechanisms of this type may be provided for shifting the position ofthis belt for the purpose of regulating the speed of the press. Theother units may be similarly provided with connecting belts andbelt-shifting devices.

I have pointed out specifically the arrangement of the driving mechanismfor but one of the units as all of them are of substantially the sameconstruction and arrangement and it is therefore to be understood thatthis description applies to the other units as well as the press to. Theoperation of this arrangement is obvious. The countershafts under themachine are driven by the rope-drive arrangement which I have describedand the various units of the paper making machine are driven directlyfrom these countershafts by the cone pulleys and their connecting belts.

Hitherto paper making machines have been driven by an engine situatedbeneath the operating floor, the motive power of which is transmittedthrough long lines of countershafting, and a cumbersome system ofgearing which included at least one pair of bevel-gears for each of theunits of the machine. The space underneath the floor of the machine wasso much encumbered by this mechanism that it was not available for otheruses. By my arrangement the countershafts which drive the various unitsare supported from the floor leaving the floor of the basement free forthe most part, or are supported from the roof of the engine-room and therope-drive transmission may be placed close to this roof. This leavesthe floor space clear except for the portion of the floor which is takenup by the driving engine, and in some cases even this space may be leftclear by using an electric motor suspended overhead for driving the countershaft 93 and the rope-drive mechanism. Another advantage of thisarrangement is that the spur gears and driving cones which I use take upbut little space upon the operating floor and these may be entirelyinclosed by a waterproof cover placed over them in the position shown at40 in F 6 and by the dotted lines in Fig. 3. When such covers are usedthe entire driving mechanism is so protected that the operating floorand various parts of the paper making machine may be readily cleaned bymeans of a hose. The floor space saved by this arrangement is so greatthat in a certain case it has been possible to install a large modernpaper making machine in a building constructed for a much smallermachine which could not have been done with any of the devicesheretofore known without reconstructing the building.

The various units of a paper making machine must be positively driven atrelative speeds to each other.

It is essential in a machine of this character that the various unitsshall be driven smoothly and with entire freedom from any jerky motion.This arrangement entirely overcomes difficulties of this character whichare often disastrous as they break the paper during the process of itsmanufacture and cause expensive delays. The peculiar arrangement whichI'have invented for supporting the units upon the floor and the peculiardesign of driving mechanism for the various units makes a cheap form ofinstallation. Moreover, as many parts'of the construction may be usedfor each of the units, it makes feasible the carrying of but few repairparts and thereby increases the efliciency of the machine.

What I claim is.
